慢sql进行 手动分页

com.meipingmi.yunyikuoperation.common.page.Page page = new com.meipingmi.yunyikuoperation.common.page.Page();
page.setPageSize(ordersAO.getPageSize());
ordersAO.setOffSet((ordersAO.getPageIndex() - 1) * ordersAO.getPageSize());

		<if test="offSet != null">
			limit #{offSet} , #{pageSize}
		</if>


 List<OrderListDTO> orderListDTOs = this.ordersMapper.listByCondition(ordersAO);
 page.setList(orderListDTOs);
 page.setTotal(ordersMapper.selectCountForlistByCondition(ordersAO));
 return ResultObject.success(page);
